摘要： 背景　情绪行为问题是孤独症最常见的伴发精神症状。目前我国关于孤独症幼儿伴发的情绪行为问题的研究较少。目的　利用Achenbach儿童行为量表（CBCL）（2~3岁版）评估孤独症幼儿的情绪行为问题。方法　选择在2016年2月—2017年2月于北京大学第六医院课题组专家门诊连续就诊且符合美国精神障碍诊断与统计手册第4版（DSM-Ⅳ）孤独症诊断标准的孤独症幼儿116例为孤独症组；2016年6月—2017年2月，按照1∶1.5的比例，选择性别、年龄与孤独症组相匹配的北京市幼儿园健康幼儿174例为正常对照组。由两组幼儿的父母或主要抚养人填写CBCL（2~3岁版）。对比两组CBCL（2~3岁版）评分及CBCL（2~3岁版）各因子评定阳性率。结果　孤独症组CBCL（2~3岁版）总分和内化分量表、外化分量表评分及各因子（社会退缩、抑郁、躯体主诉、睡眠问题、攻击行为、破坏行为）评分高于正常对照组（P<0.05）。孤独症组社会退缩、抑郁、躯体主诉、攻击行为、破坏行为因子评定阳性率高于正常对照组（P<0.05）；孤独症组睡眠问题因子评定阳性率与正常对照组比较，差异无统计学意义（P>0.05）。结论　与正常幼儿相比，孤独症幼儿存在较多的情绪行为问题，主要为社会退缩、抑郁、攻击行为等。应对孤独症幼儿的情绪行为问题予以关注。
